I just wonder what these simple equations are called in English? Do they have professional names/terminologies in math?
equation 1: x = a + b - c
equation 2: x = a * b / c
The key is the sign, equation 1 only contains plus and/or minus signs. Equation 2 contains only Multiplication and division signs. a, b, and c are variables, they could be a complex term, or a single known or unknown value.
So, what do I call these two types of equations in English? I know the first one might be called a linear equation, but how about the second one?
